<A name="agentlog"><h2>AgentLog</h2></A>
<!--%plaintext &lt;?INDEX {\tt AgentLog} directive&gt; -->
<strong>Syntax:</strong> AgentLog <em>file-pipe</em><br>
<strong>Default:</strong> <code>AgentLog logs/agent_log</code><br>
<Strong>Context:</strong> server config, virtual host<br>
<strong>Status:</strong> Extension<br>
<strong>Module:</strong> mod_log_agent<p>

The AgentLog directive sets the name of the file to which the server will
log the UserAgent header of incoming requests. <em>File-pipe</em> is one
of
<dl><dt>A filename
<dd>A filename relative to the <A HREF="core.html#serverroot">ServerRoot</A>.
<dt> `|' followed by a command
<dd>A program to receive the agent log information on its standard input.
Note the a new program will not be started for a VirtualHost if it inherits
the AgentLog from the main server.
</dl>
<strong>Security:</strong> if a program is used, then it will be
run under the user who started httpd. This will be root if the server
was started by root; be sure that the program is secure.<p>

<strong>Security:</strong> See the <A
HREF="../misc/security_tips.html">security tips</A> document for
details on why your security could be compromised if the directory
where logfiles are stored is writable by anyone other than the user
that starts the server.<P>

This directive is provided for compatibility with NCSA 1.4.<p>
